Potential impact of CO2 emissions on the seafloor (original) (raw)

Abstract

Carbon Capture and Storage (CCS) aims to capture CO2 from fossil-fuel sources, transport and store it in suitable geological formations where it will be confined for extremely prolonged times. This is considered a feasible way of mitigating global warming. The seafloor is one of the target areas to safely store large volumes of anthropogenic CO2 through the development of sub-seabed CO2 geological storage. For the UK and large parts of Europe, the North Sea is potentially the most suitable location for CCS projects required to achieve planned targets in the reduction of CO2 emission. Other sub-seabed areas are studied for their storage potential in America and Asia. Even if the technology is considered proven, following the experience gained from the oil industry in using CO2 for enhanced oil recovery (EOR), and a few CO2 storage pilot projects, the risk of CO2 seepage must be addressed considering potential consequences on the marine environment. CO2 emissions may affect the seaflo...
